Question about Kicker Solo-Baric L7 S15L72 Car Subwoofer

1 Answer

I turned my 15" L7 kicker and smoke started to come out the box

My radio goes from -24 to +6 for the subwoofer and i had it 0 and i have a 100 fuse amp on the sub. I have a 1000.1 KICKER AMP and i had the bass on the bass knob all the way up. I turned the volume to about 50 ( it goes to 63) and smoke started to come out of the port slot on my box.

    It sounds like you almost/or did blow (short) your kicker sub.

    another reason why it came smoke out of our box could be:

    - the damping material in the box got to close to the cone
    - the box got a passive crossover filter that got smoked.

    but it sounds like you maxed the performance of your speaker.

    did you ever try putting a jigsaw puzzle together without all of the pieces? that's what we have here. Need more input. we troubleshooters need as much info as you can give us.

    1. did you use high or low level inputs on the amp?
    2. which L7 sub? is it dual voice coil? 2 or 4 ohm?
    3. smoke from the port slot of what box?

    get back to me & we'll see what we can do.

    peace-out

As stated before, knowing the impedance of your subwoofer would really help the situation. Either way the link I have provided is to your subwoofers manual (Incase you dont have it)

But since you have said it has smoked, if it still works I recommend turning the bass boost down (Bass boost causes alot of heat within the subwoofers voice coil and even within the amp itself and should never be maxed out.)

Here is a link to your manual for the subwoofer.
http://www.kicker.com/sites/default/files/SoloBaricL7Series.pdf

So as a solution to your issue, keep your bass boost turned down. You should almost never need it if you have tuned your amp correctly (You have a very serious subwoofer there)

Consider yourself lucky if your subwoofer is still working without issues.

@aol.comI have a kicker zx 1500.1 amplifier and a 15 inch L7 2ohms. Is the amp too much for it?


the amplifier is never to much for the sub. If the gain on the amp is turned up to much then that will pop the sub.

My kicker 12 inch solo-baric L7 rattles real bad like something is loose but there is nothing visibly loose what could it be ?


Its blown. Maybe not completely but youve done some damage. If your sure its not hitting the box anywhere and its tight, then thats what it is. Youve burnt the voice coils a little. They regulate how far the sub goes in and out. I have two kicker L7 12s that have bad voice coils. And thats what they do. Theyre in my trunk though so its not to noticeable and they still hit super hard. -->

Also it could be the seal for the box. They wear out and boxes get leaks or weak causing flexibility in the material so when subs hit it vibrates the box really bad. Try removing she speaker from the box then turn it up and see if it makes the noise. If not then its probably the box. Let me know.

I need the basket gasket for 15'' l7


The only way to get a new one is to contact Kicker directly, and see if they'll sell you one. Otherwise, you'll need to get another woofer. They only sell the replacement parts for the SoloX woofers. Sorry about that.

How to run the speaker wires to connect to the subwoofer? and does a sub woofer burn if you do not put the right ammount of watts to it for example having an kicker l7 connected to a three houndred watt...


i'm guessing you are having problems with the dual voice coil's so I will link you to the kicker wiring guide...

http://kicker.com/sites/default/files/SoloBaricL72006.pdf that has the wiring options, you will need a pdf reader **** as adobe or foxit..

Under powering your subs won't hurt them but running a 15 inch l7 at 300 watts is not going to let the sub perform at peak, I would go with a 800 to 1000 watt amp.

15 inch l7 watt's are as follow

rms = 1000
peak = 2000

I have a brand new L7 is it blown?


check to make sure your box is securely sealed and that the box itself is not rattling. if not, most subs require a break in period where they can not be played full gain/full volume for the first 48 or so hours... did you break in your subs by paying it softly the first day and slowly turning your amps gain and receivers volume up the next couple of days. if not, it is likely blown

Hi yeahonda,

 

Your Kicker L7 Ohms may be too low for the MA Audio Mono block amp. The MA Audio Amp is probably 2 Ohm Stable. The kicker will either be 2 ohm or 4 ohm Dual voice coil.   To eliminate the low ohms as a possible threat to causing the map to go into Protect, Wire the kicker Voice Coils in Series.  This adds the ohms, so that you either have 4 or 8 ohms. 

I am using the following codes to show wiring. VC1+ stands for the Kicker  Subs Voice Coil #1 Postive post. AO+ is the MA audio Amp output positive.

 

AO+ to VC1+

VC1- to VC2+

VC2- to AO-

 

This shopuld give you 4 or 8 ohm depending on the 15" L7 setup.  Crutchfield does not carry the Kicker  L7 in 15" They do  have the L5 in 15".

 

If you know how to read a Volt Ohm Meter, set it to OHMs 20 and measure across VC1+ to VC1- and you should see between 1.5 and 5 ohms..  Do the Same with VC2+ to VC2-.  you should see the same voltage. Also read from the Voice coil metal housing to VC1+ , VC1-, VC2+, and VC2-. and you should not read any ohmage to the case. The meter should say OL, or -1.

Good luck.
